The only one that is number one is SpaceX (and Starlink, if you count that separately).

None of the neuroscience people I follow think much of Neuralink; none of the civil engineers I've talked to IRL think much of TBC; none of the car people I follow favour Tesla over the huge range of competitors, and that includes the robo-taxi where they're about 6.5 years behind Waymo; X.com is so painful that whenever someone shares a link with me, I edit the URL to Xcancel.com *because that loads faster by a bigger margin than the time taken to edit the URL* and actually shows me the thread without needing an account of my own.

But the space nerds I follow are still impressed with SpaceX, and they have extremely obvious reasons to be impressed.
